Using the function f(x) = 2x + 7 find the following: (show your work) f(2) and f(7)

Ksju [112]

All you have to do is substitute 2 and 7 in for x in the function.

f(2) = 2(2) + 7

= 11

f(7) = 2(7) + 7

= 21

Determine the quadratic equation with roots

zvonat [6]

Answer:

$y=6x^2-5x+1$

Step-by-step explanation:

If the quadratic equation has a root at $\dfrac13$ then when $x=\dfrac13$ , $y=0$

$\implies x=\dfrac13$

$\implies 3x=1$

$\implies 3x-1=0$

If the quadratic equation has a root at $\dfrac12$ then when $x=\dfrac12$ , $y=0$

$\implies x=\dfrac12$

$\implies 2x=1$

$\implies 2x-1=0$

Therefore, $y=(3x-1)(2x-1)$

$\implies y=6x^2-5x+1$
